quality inspection is an indispensable part of modern industrial manufacturing. steel as a major industry requires constant surveillance and supervision through its various stages of production. continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. once the slab is released from the casting unit, th...

Modern science relies on simulation techniques for understanding phenomenon, exploring design options, or evaluating models. Assuring the correctness of simulators is a key problem where a multitude of solutions ranging from manual inspection to formal verification are applicable. Formal verification incorporates the rigor necessary but not all simulators are generated from formal specification...

This paper considers ways of modelling time dependent inspection problems where there is a possibility of false alarms. For this purpose, it is assumed that safeguards procedures are notified to the inspectee by the inspector and are prima facie plausible ones. This 'inspector-leadership principle' implies that under reasonable assumptions the inspectee's strategy is legal in the sense of compl...

OBJECTIVE To conduct a retrospective analysis on cases undergoing inspection of orthopedic damage, at an orthopedic emergency service in a teaching hospital, with the aim of evaluating patients with postoperative infection after conversion to internal osteosynthesis. METHODS This was a retrospective analysis covering the period from June 2012 to June 2013, on patients who underwent inspection...

We present a spectral domain low-coherence interferometry (SD-LCI) method that is effective for applications in on-line surface inspection because it can obtain a surface profile in a single shot. It has an advantage over existing spectral interferometry techniques by using cylindrical lenses as the objective lenses in a Michelson interferometric configuration to enable the measurement of long ...

A high-speed sorter was used to remove kernels infected with Karnal bunt from 1800g wheat samples. When the sorter removed about 8% or more of the sample, the reject portion contained 100% of the bunted kernels. Concentrating the bunted kernels in a smaller sample size will reduce sample inspection time and should reduce inspection errors. One high-speed sorter can process up to 8800 kg/hr, thu...

This paper presents a heuristic method for evaluating virtual environment (VE) user interfaces. The method is based on Nielsen’s [Usability Inspection Methods, 1994] usability heuristics, extended by VE-specific principles proposed by Sutcliffe and Kaur [Behaviour and Information Technology 19 (2000) 415–426]. Twelve heuristics are presented which address usability and presence issues. An inspe...

Recently developed optical inspection tools provide images from the inside of natural gas pipelines to monitor pipeline integrity. The vast amounts of data generated prohibits human inspection of the resulting images. We designed an image processing and classification method to identify abnormal events. Non-overlapping image blocks are classified into twelve categories: normal, black line, grin...

Packaging is one of the important aspects product. Good packaging can increase competitiveness a Therefore, to maintain quality product, it necessary have visual inspection. Furthermore, an automatic inspection reduce occurrence human errors in manual process. This research will use convolution network detect and classify PET (Polyethylene Terephthalate) bottles. The Convolutional Neural Networ...
